It is fixed to the holding portion 14 of 10, and is formed in a nut shape having a female screw (not shown) that is screwed with a male screw. The second connecting body 26 has an outer diameter slightly larger than the diameter of the hole 14a of the holding portion 14.

The faucet metal fitting 30 is a discharge hole having a valve for water supply control such as a single water faucet or a mixed water faucet in a water supply facility.
It has a male screw 30a to be screwed with the female screw 4a of the water faucet coupling portion 3. In addition, 32 is a wall body, 32a is a wall hole, and 33 is a construction material.

Next, the construction procedure of the faucet mounting device 1 will be described with reference to FIG. First, the box body 10
Is fixed to the building material 33 inside the wall body 32, one end of the flexible corrugated pipe 22 is fixed to the connector 23, and the connector 23 is fixed to the holding portion 14 of the box body 10. On the other hand, the other end of the flexible corrugated pipe 22 is laid down to a header or the like connected to the main pipe portion, and the water supply pipe 21 is inserted into the flexible corrugated pipe 22 and guided to the inside of the box body 10. . Next, the water supply pipe 21 guided inside the box body 10 was once pulled out from the opening 11a of the attachment part 11 of the box body 10, and the end of the water supply pipe 21 was connected to the water supply connection part 6 of the joint 2. Then, the joint 2 is inserted into the box body 10 through the opening 11a, and the water faucet connecting portion 3 of the joint 2 is attached to the attachment portion 11 of the box body 10.

Next, the pipe cover 15 is attached to the wall hole 32a. First, the cover body 16 and the locking bodies 17b, 17
With the spacing of b larger than the thickness of the wall 32, and rotating around the fasteners 17a, 17a so that the locking bodies 17b, 17b pass through the wall holes 32a, the first penetration of the cover body 16 is performed. Hole 16a
The pipe cover so that it is located in the faucet connection part 3 of the fitting 2.
Hold 15 on top of wall hole 32a. In that state, the fastener 17a,
When 17a is rotated clockwise, the locking members 17b, 17b are urged by the spring members 17d, 17d in the direction to open the gap with the cover body 16.
Is moving toward the cover body 16 while moving the fastener 17
It rotates together with a and 17a, and when it comes into contact with the back surface of the wall 32, the rotation stops due to friction. Therefore, further fastener 17
By rotating a and 17a in the clockwise direction, the distance between the cover body 16 and the locking bodies 17b and 17b becomes shorter, and the pipe cover 15 is attached to the wall hole 32a. In this state, the male screw 4a of the faucet fitting 30 is connected to the faucet coupling portion 3 of the joint 2.

This faucet mounting device 1 includes a second water blocking member 19
However, the second water shut-off member 19 is provided between the pipe cover 15 and the faucet coupling portion 3 of the joint 2 even when the wall 32 has a different thickness, because the second water shut-off member 18 can be compressed and deformed to a greater extent. Since it can be interposed while being compressed, regardless of the thickness of the wall body 32, it is possible to prevent water from entering from the front side to the back side. Also, by rotating the fasteners 17a, 17a, the locking body 17
b and 17b are locked to the back surface of the wall 32 and the cover body 16 is
Since the first and second water blocking members 18 and 19 are fixed on the surface of the wall body 32 or the faucet connecting portion 3 of the joint 2 without rotating, the first and second water blocking members are fixed. Member 18,19
Is properly compressed without kinking, resulting in improved waterproof performance.

Next, a second embodiment of the present invention will be described with reference to FIGS.
It will be described based on. This embodiment is different from the first embodiment in the structure of the second water blocking member 19.

The second water blocking member 19 is formed of a substantially cylindrical shape by an elastic member that can be compressed and deformed to a greater extent than the first water blocking member 18. Specifically, the second water blocking member 19 is formed of a bellows-shaped rubber material so as to have a corrugated outer peripheral wall in which a large number of peaks and valleys are alternately arranged in the axial direction. ,
It is attached to the second attaching portion 16c of the cover body 16 and compressed by the attaching piece 5 of the water faucet connecting portion 3 of the joint 2.
The thickness is set so as to project considerably from the back surface of the cover body 16 when attached to the 16c.

Since the shape of the second water blocking member 19 is stable and easy to assemble, the productivity of the pipe cover 15 is improved.

The structure of the piping cover is
Although it has been described as having the fastener, the locking body, and the spring member, the structure is not limited to this, and a structure such as a conventional example may be used. Anything that can be worn is acceptable. In addition, the first water blocking member,
Although it is formed of a normal rubber material, of course, it may be formed of a rubber material having closed cells or a bellows-shaped rubber material.

[0034]

In the water faucet mounting device according to the first aspect of the present invention, since the second water blocking member can be compressed and deformed to a greater extent than the first water blocking member, the second water blocking member can be deformed even when the wall thickness is different. Since the water member can be interposed between the pipe cover and the water faucet connecting portion of the joint while being compressed, it is possible to prevent the water from infiltrating from the front side to the back side regardless of the thickness of the wall body.

Further, in addition to the effects of the first aspect, the water faucet mounting device according to the second aspect can be easily manufactured because the first water blocking member is made of a rubber material having closed cells. Therefore, the cost can be reduced.

Further, in addition to the effect of the first aspect, the water faucet mounting device according to the third aspect is constructed such that the first water blocking member is formed of a bellows-like rubber material, so that the shape is stably assembled. Since it becomes easier, productivity is improved.

Further, in addition to the effects of claims 1 to 3, the faucet mounting device according to claim 4 rotates the fastener to cause the locking body to lock on the back surface of the wall body and the cover body. Is fixed to the wall body, the first and second water blocking members are compressed at the surface of the wall body or at the faucet connecting portion of the joint without rotating, so that the first and second water blocking members are It is properly compressed without kinking, resulting in improved waterproof performance.

In addition to the effect of the fourth aspect, the water faucet mounting device according to the fifth aspect is in a state of being inserted into the wall hole of the wall body by rotating the locking body around the fastener. Therefore, the assembling property of the pipe cover is improved, and the construction becomes convenient.
